Zero-Telemetry Crypto Portfolio Tracker
Your Data Never Leaves Your Device

Chainfolio is architected from the ground up for absolute data sovereignty. No analytics trackers, no accounts, no KYC, no cookies, no servers. Your portfolio intelligence belongs to you—and only you.

Not your keys, not your crypto. But what about your data?

While traditional trackers sell your wallet data to hedge funds and spam you with ads, Chainfolio follows a radical principle: zero-telemetry by design.

What Zero-Telemetry Really Means

No Analytics Trackers

Chainfolio contains zero third-party analytics code. No Google Analytics, no Mixpanel, no Amplitude, no crash reporters, no cookies sent to external domains.

  • No fingerprinting scripts
  • No session recording
  • No A/B testing telemetry
  • No "anonymous" usage statistics

No Accounts, No KYC

Chainfolio has no concept of "users". There is no account creation, no email collection, no password database, and no server-side authentication.

  • Anonymous by architectural design
  • No personal information ever requested
  • No tracking of who uses the app
  • No "free tier" vs "premium" user segmentation

Local-First Architecture: How It Works

Three-Layer Data Persistence

1. Hot Layer (In-Memory)

Real-time UI updates – UI state that updates instantly as you interact.

  • Current portfolio balances
  • Live chart data
  • Active alerts and notifications

2. Warm Layer (localStorage)

Browser localStorage / Capacitor Preferences – User preferences and configuration.

  • Wallet addresses being tracked
  • RPC endpoint configurations
  • Alert definitions and thresholds
  • UI theme and layout preferences

3. Cold Layer (IndexedDB)

Encrypted local database – All historical data, encrypted at rest.

  • Time-series portfolio snapshots (19,500+ per demo)
  • Transaction history with smart classification
  • RPC health and latency metrics
  • Whale directory and tracking data

AES-Encrypted Cloud Backups (Optional)

Chainfolio offers optional encrypted backups to cloud storage providers—with a critical distinction: encryption happens locally before any data leaves your device.

Supported Cloud Providers

  • Google Drive
  • Microsoft OneDrive
  • Dropbox
  • Box
  • Any WebDAV-compatible storage

Encryption Process

  1. All local data is serialized and compressed
  2. AES-256 encryption is applied using a key derived from your passphrase
  3. Encrypted blob is uploaded to your chosen cloud provider
  4. Chainfolio never sees your passphrase or unencrypted data

BYOK – Bring Your Own Key Infrastructure

Chainfolio ships with no hardcoded API keys. You provide:

RPC Endpoints

Ethereum (Alchemy, Ankr, Infura) and Solana (Helius, QuickNode, custom) endpoints.

Etherscan API Key

Optional for higher rate limits on Ethereum transaction fetching.

Cloud Storage

Your own Google Drive, OneDrive, Dropbox, or Box account for encrypted backups.
